NGC 1499 as an animated 3D
Animations are made by creating artificial parallax to an image. Then two images are animated together by using conversion web service, Start3D. There can be some artifacts in images, due the experimental nature of this work! The volumetric models are based on some known facts and an artistic impression.
Please, let the images load for few seconds to see them animated!

Sh2-234, IC417, Project finalized
from the emission of ionized elements, R=Sulfur, G=Hydrogen and B=Oxygen.
Distance is about 10.000 light years. Image is about 30' wide and covers about 100 light years.
Ra 05 hr 28 min 05.9 sec , Dec +34 hr 25 min26 sec
This is not too commonly imaged target due the lowish surface brightness and the proximity of two eye catchers, IC 405 and IC 410. This image was one of the most difficult one to process due the very weak signal. There was some very dim O-III emission in the target, it can be seen as a Blue.
Technical details:
Processing work flow:
Image acquisition, MaxiDL v5.07.
Stacked and calibrated in CCDStack.
Deconvolution with a CCDSharp, 30 iterations, 50% mix..

Sh2-234 aka IC 417, start of the new project.
Sh2-234, IC417, sometimes called as "Spider Nebula", in constellation Auriga. H-alpha 15x1200s.
Distance is about 10.000 light years. Image is about 30' wide and covers about 100 light years.
Ra 05 hr 28 min 05.9 sec , Dec +34 hr 25 min26 sec
This is not too commonly imaged target due the lowish surface brightness and the proximity of two eye catchers, IC 405 and IC 410. Sh2-234, contains a young open star cluster that ionizing the surrounding gas.
I will shoot more lights for this object later, including O-III and S-II data.

NGC 1499, reprocessed
I did reprocessed this nebula since my skills are much better now, than two years ago.
All the exposures I have taken for this object are used. Total exposure time is now about 20h together.
Two camera lenses was used to capture the data, a Tokina AT 300mm f2.8 and a Canon EF 200mm f1.8, both lenses was used at full aperture.
NGC 1499, the "California Nebula" locates in constellation Perseus. Distance is about 1000 light years.
The nebula covers about 2,5 degrees of sky.
RA 04h 03m 18.00s Dec +36° 25′ 18.0"
Natural color composition from the emission of ionized elements, R=80%Hydrogen+20%Sulfur, G=100%Oxygen and B=85%Oxygen+15%Hydrogen to compensate otherwise missing H-beta emission. This composition is very close to a visual spectrum.

from the emission of ionized elements, R=Sulfur, G=Hydrogen and B=Oxygen.
Narrowband data was used for Star colors this time, mixture of channels was the same as in first "natural" color composition image here.
There is a formation at Seven a clock, kind of half circle, it might be an old uncategorized planetary nebula?

NGC 1499, the "California Nebula", a closeup
NGC 1499, the "California Nebula" locates in constellation Perseus. Distance is about 1000 light years.
This is a closeup image, the actual nebula covers about 2,5 degrees of sky.
RA 04h 03m 18.00s Dec +36° 25′ 18.0"
The image is in HST-palette, (HST=Hubble Space Telescope)
from the emission of ionized elements, R=Sulfur, G=Hydrogen and B=Oxygen.
I have shot this image as a wide field version before. For this closeup I shot 27x1200s, binned down 2x2, for H-alpha channel, colors are from my older wide field image. NGC 1499 has a very low surface brightness, hence a longish integration time is needed.

Original Blog post and details:
This image was published at July 2009 issue of Sky & Telescope magazine's Gallery, in page 78,
there is a full page image of NGC 1499, the "California Nebula" by me.
Total exposure time is 18 hours.

IC 405, project finalized
IC 405, Sh2-229 or Caldwell 31 also known as the "Flaming Star Nebula".
RA 05h 16.2m dec +34° 28′
Image is in HST-palette, (HST=Hubble Space Telescope)
from the emission of ionized elements, R=Sulfur, G=Hydrogen and B=Oxygen.
IC 405 locates in constellation Auriga and it's an emission/reflection nebula. Refelction component can't be seen in my image, since I'm shooting only narrowband data and reflection part is broadband target.
Distance from Oulu, Finland, is about 1500 light years. Nebula is about 5 light years across.
Total exposure time is about 12h
